IMPROVEMENT IN LAMP-EXTINGUISHERS.

Specification forming part of Letters Patent No. 1 72,035, dated January 11, 1876 application filed December 4, 1875.

To allwhom it may concern Be it known that I, CHARLES J. KNAPP, of the city, county, and State of New York, have invented a new and Improved Lamp-Extinguisher, of which the following is a specification:

Figure 1 represents a side elevation of a burner with my improved extinguishing de vice and Fig. 2 is a vertical transverse section, and Fig. 3 a top view, of the same.

Similar letters of reference indicate corresponding parts.

My invention relates to a simple, reliable, and effective extinguishing device for lampburners, that may be easily handled so as to extinguish the flame in an instant.

My invention consists of posts or standards, which are applied to the narrow sides of the wick-tube, and provided at the upper ends with pivoted caps that are operated to close over the wick-tube, or opened by aforked and weighted or spring-acted lever with cap-connecting links.

In the drawing, A represents a lampburner of any suitable construction; B, the wick tube, and O the posts or standards that are secured to the narrow sides of the same, running up to nearly the same height therewith. Two caps, D, are pivoted symmetrically at bothsides oflthe Wick-tube to the upper ends of the posts, and connected by hinged butts a to the forked ends I) of a weighted or spring-acted lever-handle, E, that is fulcrumcd to the base-plate of the lamp-burner, and extended to some distance beyond the outer periphery of the same.

The forked ends b of the lever are parallel to the wick-tube, and engage, by their hook-bent ends, the eyes of the cap-connecting links, so

as to slide readily therein when the leverhan- I am aware that caps closing over the flame of a candle or lamp to extinguish the same have been used heretofore, and I therefore do not claim the same broadly; but I claim the pivoting of the caps to side posts of the wicktube, as thereby a strong support to the caps is given, and the regular and effective working of the same obtained, they being not affected by the infliience of the heat, or worked by springs thatsoon get out of order and useless.

Having thus described my invention, I claim as new and desire to secure by Letters Pat-' ent The caps'D D,pivoted on each side of wicktube to the upper ends of posts (3 C, and connected by hinged links a with ends of an autoinaticallyopenin g lever, as and for the purpose specified.

GHARLES J. KNAPP.
